[Tkinter-discuss] Graying out and disabling widgets that are not selected

[Peter Milliken]

I have done something similar in an application (broadly speaking of course
:-)). 
 
I used Pmw for my application but the same should be true of using tkinter
elements (I find that Pmw provides a very nice model when it comes to
controlling and using groupings of GUI elements - 'configuration' of them
(assuming you create classes that inherit from Pmw.MegaWidget) becomes very
flexible and powerful as it fits right in which the OO model).
 
Create a class which "manages" the display elements. Have the action events
of each GUI element point to a different method of the class and make the
appropriate actions in that method to control which elements are "grayed
out" and which aren't.

Hi everyone,
 
I have a problem which, while probably simple for most of you, I am having a
hard time figuring out.
 
For the sake of argument, let's say that I create an entry field and two
comboboxes.  I want the application to gray-out and disable the two
comboboxes if typing occurs in the entry field.  Likewise, if an item is
selected from one of the comboboxes, I want to gray-out and disable the
entry field and the other combobox.
 
Any ideas?
 
Thanking you in advance,
 
Christopher Nethery
